Question

我正在使用以下代码。当网站用户填写表单时，我收到的电子邮件不会显示用户在文本区域（message_content）中添加的换行符。如何实现这一点，以便消息内容的布局在电子邮件中看起来相同。

autosize(document.querySelectorAll('#message_content'));



var validator = $("#comment_form").validate({
  ignore: [],
  rules: {
    gender: {
      required: true,
    },
    first_name: {
      required: true,
      minlength: 2
    },
    last_name: {
      required: true,
      minlength: 2
    },
    email: {
      required: true,
      email: true,
      minlength: 4
    },
    email_again: {
      equalTo: '[name="entry[email]"]'
    },
    message_subject: {
      required: true,
      minlength: 2
    },
    message: {
      required: true,
      minlength: 4
    },
    hiddenRecaptcha: {
      required: function() {
        if (grecaptcha.getResponse() == '') {
          return true;
        } else {
          return false;
        }
      }
    }
  }
});

Answer 1

您的电子邮件是HTML电子邮件，因此您需要发送HTML换行符。在要使用换行符的所有输入上使用nl2br。

$message_content = !empty($_POST['message_content'])?nl2br($_POST['message_content']):'';

在在线表单发送的电子邮件中，请注意输入到表单文本区域的换行符
